Method for providing radio frequency identification application interface and system thereof

Abstract

The present invention relates to an RFID application interface method and a system thereof. In the present invention, an RFID middleware system changes a control request input from a user or an RFID application system according to a communication protocol of an RFID device to be controlled, and sends it to the RFID device. Also, when the user or the RFID application system inputs a data process policy that is common to various RFID devices of a logical RFID device group, the RFID middleware system generates data process rules that are suitable for communication capability and data processing capability of each RFID device based on the data process policy and provides an interface that allows processing of data by a corresponding RFID device. In addition, the RFID middle system defines a procedural flow of at least one of services and at least one of tasks that constitute an RFID business process and provides an interface to support interconnection and cooperation of services that are included in the RFID business process.
